Tutorial: Microsoft Entra SSO integration with Pluto

  • Article

In this tutorial, you'll learn how to integrate Pluto with Microsoft Entra ID. When you integrate Pluto with Microsoft Entra ID, you can:

  • Control in Microsoft Entra ID who has access to Pluto.
  • Enable your users to be automatically signed-in to Pluto with their Microsoft Entra accounts.
  • Manage your accounts in one central location.

Prerequisites

To get started, you need the following items:

  • A Microsoft Entra subscription. If you don't have a subscription, you can get a free account.
  • Pluto single sign-on (SSO) enabled subscription.
  • Along with Cloud Application Administrator, Application Administrator can also add or manage applications in Microsoft Entra ID. For more information, see Azure built-in roles.

Scenario description

In this tutorial, you configure and test Microsoft Entra SSO in a test environment.

  • Pluto supports SP initiated SSO.
  • Pluto supports Just In Time user provisioning.

Note

Identifier of this application is a fixed string value so only one instance can be configured in one tenant.

To configure the integration of Pluto into Microsoft Entra ID, you need to add Pluto from the gallery to your list of managed SaaS apps.

  1. Sign in to the Microsoft Entra admin center as at least a Cloud Application Administrator.
  2. Browse to Identity > Applications > Enterprise applications > New application.
  3. In the Add from the gallery section, type Pluto in the search box.
  4. Select Pluto from results panel and then add the app. Wait a few seconds while the app is added to your tenant.

Alternatively, you can also use the Enterprise App Configuration Wizard. In this wizard, you can add an application to your tenant, add users/groups to the app, assign roles, as well as walk through the SSO configuration as well. Learn more about Microsoft 365 wizards.

Configure and test Microsoft Entra SSO for Pluto

Configure and test Microsoft Entra SSO with Pluto using a test user called B.Simon. For SSO to work, you need to establish a link relationship between a Microsoft Entra user and the related user in Pluto.

To configure and test Microsoft Entra SSO with Pluto, perform the following steps:

  1. Configure Microsoft Entra SSO - to enable your users to use this feature.
    1. Create a Microsoft Entra test user - to test Microsoft Entra single sign-on with B.Simon.
    2. Assign the Microsoft Entra test user - to enable B.Simon to use Microsoft Entra single sign-on.
  2. Configure Pluto SSO - to configure the single sign-on settings on application side.
    1. Create Pluto test user - to have a counterpart of B.Simon in Pluto that is linked to the Microsoft Entra representation of user.
  3. Test SSO - to verify whether the configuration works.

Configure Microsoft Entra SSO
